Atrend Bbox Single Sealed 12 Inch Subwoofer Enclosure - Car Subwoofer Boxes & Enclosures - Premium Subwoofer Box Improves Audio Quality, Sound & Bass - Red & Black Spring Terminals - Charcoal

Box is sturdy and solid. Clean cuts, well glued. For the price paid, fantastic.

Great box for the price. Well made. Sounds great. Looks great. Fits in the back seat of my pickup.

Was a perfect fit in my Grand Marquis to have a small subwoofer and the price is actually good and it seems quality enough for what I'm doing. The sub was finicky to put in but that's not the boxs problem. The main and really only problem I ran into was the included terminals and wire gauge used on the terminal case. Waaay too small for my comfort level on a 500 watt rms subwoofer. So I had to take the terminal case on and solder on larger wires. After that it's functioning as I prefer and is the perfect size for the space as seen in the pictures if I post any.

The quality of this box is fairly good for the price and produces tight and punchy bass paired with my 15” Boston Acoustics G215-44. The box was shipped in a thin cardboard box with no additional padding or protection. Mine was not damaged in any way but I wish they would at least put some hard foam padding on the corners to prevent damage from accidental falls or dings during shipping. Using a pair of calipers, the baffle measured 1” as claimed and the side walls measure about 13/20” (0.65”). This is probably sufficient for most 15” subwoofers as long as it isn’t a triple magnet, 10000 watt monster sub. I measured and posted a picture with the dimensions so you can make sure it fits before you buy. Internal volume measures roughly 3532 cu in or 2.04 cu ft. (as claimed). As far as installation, my sub dropped right in with no sanding or modification. This one has spring loaded terminals which I am not a fan of but It can easily be replaced with any number of binding post terminals here on amazon or parts express. I lined the box with roughly 10 sq ft of 2” thick fiber glass insulation to help dampen standing waves. Also, the ugly “BBOX” emblem on the lower corner can be pried off with a flathead screwdriver it it bothers you. And as a general tip when installing, predrill the holes for the sub so that you don’t split the wood when fastening the screws.

Bass sound awesome, for this 8" woofer box. Get it. You will love it.

This is a reallly good box for the price, can't go wrong. As another reviewer said, the description is a little misleading as part of the construction is 3/4" mdf (as advertised) and part is only 1/2" mdf. I sprayed the interior with plastidip to sort of thicken it up and prevent vibration, although I'm not sure if that was necessary, it does seem well built and glued together. Porting frequency seems a tad high (see UPDATE below), maybe 45 or 50hz or even higher? ...but it's easy to lower the porting frequency with a wadded up old tshirt or a pool noodle as another reviewer suggested. In an automotive application it might be low enough, for home theater or dnb or hiphop shows maybe experiment with a pool noodle in the port *grin*. Overall, this is a fantastic box, well built, pretty compact, a real steal for under $80 shipped. ~~~ Note you will need a drill bit for speaker holes, some screws for mounting, some wire to connect your sub to the terminal. UPDATE: Confirmed the porting frequency is much too high, added it at a show to a KV2 dual 15 (one of the best sub setups) and this was literally canceling out the lowest notes of the KV2. We finally shut off this sub. BUT, that is an easy fix, partially obstruct the port with something like a pool noodle OR if you are near a wall place this sub an inch or way from the wall facing the wall. This will effectively lower the porting frequency and it won't cancel out the 35 hertz notes from your other speakers. Still great for the money! editagain: In my pic I'm using "Allstar - ALL14100 Black 3' Roll Bar Padding" to mostly obstruct the ports and the porting frequency after doing that is about 31 hertz. MMM mmmmmm (I'm guessing it was 45 or 50 hz before that, much much too high)

Sturdy, fits my JLW10 3v3 perfectly and sounds great!

Box is just ok. It sounds good, but I had a couple of issues. When I got the sub mounted, I pushed the cone and there were severe air leaks in the box. The first leak was the extremely cheap terminal on the side. It was free flowing air through the cup, mostly the spring terminals themselves. I swapped it out with a plate, but still had an air leak. I finally figured out that they had a 3/4" datto cut for the side board, but the scrap board they used wasn't quite 3/4", so they laminated it with another board that looked like 1/8" thick. When the sub would depress, the air would go into the cutout for the terminal cup, go between the layers of wood, then come out from the joint at the corner. I never got it sealed 100%, but it is close. It really does have a solid 1" mdf face board, which made for a super sturdy sub mount and homemade speaker grille mount.

What a tight beautifull low sound this box gave out when married with 12" Alpine speaker.

Well built and sounds great definitely recommend

Se ve muy bien y un excelente acabado tiene muy buena pinta

A custom box is always best but isn't always needed nor is it always in the budget of every build. For basic installs, as long as these pre fab boxes meet the volume requirements of the subwoofer you're using, they are a great option. These are very well made, have a thicker front panel which really helps when mounting heavy subs and they sound good. I have used and currently own many Atrend boxes, single ported 12, dual sealed 10 and single sealed 10. They all work very well, are compact and look good. Definitely worth the money. A custom box would have cost me about $250 and for this install in my daily driver (which I tend to change every year or so) it works just fine. I don't want to many custom boxes that are specific to a car I had as I likely won't have the car long. These are a great option.

I'm using this in my stereo system in the living room. I'm using a Planet Audio driver, and a 950W RMS Yorkville amp. I cross it over at 16Hz (slope means it works up to ~40Hz) Plug the port with a pool noodle to eliminate "chugging" though. I will never run this at full power, but it works much better than a crappy active sub that won't go down past 25Hz.
